Definitions

  • the present invention relates to gusseted reclosable plastic bags and, in particular to zipper bags made of barrier films, wherein the gusset can be fully opened and the zipper can fully close the bag
  • a bag having front and rear walls and gusseted side walls.
  • Mating zipper profiles are provided on the front and rear walls respectively and a thinned wall section is provided in the gusset portions aligned with the zipper profiles.
  • the thinned gusset wall portions may be provided in different manners.
  • the portions of the bag film material forming the gussets may be physically thinned in the areas aligned with the profiles.
  • windows may be cut in the plastic film material of the gussets in the areas aligned with the profiles, with the windows, in turn, being covered by thin film segments.
  • the gusset windows may be covered by separate strips of thin film which is free of profiles.
  • the zipper profiles may be provided on a thin carrier strip wherein segments of profiles are separated from each other by a distance equal to that of the length of the windows.
  • the carrier strip may then be attached to the bag wall, with the profile free portions of the strip covering the window openings.
  • the gussets may be open at both opposite ends of the bag or may be sealed together at one end to provide a spout at the opposite end.
  • a gusseted bag 10 in accordance with the present invention comprising a bottom 12 (which may or may not be gusseted), a front wall 14, rear wall 16 and gusseted side walls 18 and 20.
  • the top end 22 of the bag is open and closed by a zipper 24.
  • a peel seal 26 may be provided below (or above) the zipper to provide pilfer evidence and/or to permit hermetic sealing.
  • Zipper sections 24 are attached on a carrier web whose construction is depicted in Fig. 2 and consists of a carrier web 28 upon which sections of zipper with profiles 30, 32 are laid out between profile-free zones 34.
  • the profiles 30, 32 may be male and female profiles or both may be unisex. What is important is that profile section 30 be capable of interlocking with profile section 32.
  • the carrier web 28 is formed of plastic film that is relatively thin with respect to the walls of the bag so as to enable the profile-free zones to be readily captured between portions of the profiles 30, 32 when interlocked.
  • Figs. 3 and 4 wherein the zipper and carrier web 28 is depicted in position on the bag body.
  • a side 18 of the bag 10 is depicted with the gusset fully open.
  • a window 36 is cut in each of the side walls extending from edge to edge of the respective sides.
  • the edges 38, 40 of the zipper and carrier web 28 are sealed about the bag so that window 36 of one side wall is covered by one zipper profile free portion 34 of the carrier web 28 and the opposite side wall is covered by the next profile-free portion 34.
  • top and bottom marginal portions 38, 40 of the carrier web 28 are also sealed to the front and rear walls of the bag so that one of the zippers with profile portions 30 of the zipper carrier web extends along the interior of the front wall and the other of the zippers with profile portions 32 of the zipper carrier web extends across the rear wall.
  • the zipper profile free portions 34 of the carrier web extend across the gusset side walls 18, 20 in line with the profiles and cover the windows 36 and 40 cut outs of the gusset side walls.
  • gusseted side walls are closed, by folding the gussets inward about the gusset folds 50, 52, the profile free portions 34 of the carrier web are captured between the zipper profiles 30, 32 at their ends 42, 44 and 46, 48. Since the carrier web is relatively thin with respect to the remainder of the bag walls, the gusseted sides are accommodated within the interlocked profiles with relative ease.
  • the front 14 and rear 16 walls of the bag may be sealed to one another through the profiles and profile free area of the gusset side wall 20 at a side seal 53.
  • the gusset at the other side 18 may then be fully opened and inverted, as shown in Fig. 8 to form a convenient pour spout 54 for the bag.
